Hello,

I have been testing the IPv6 beta of version 2.0 and I had some problems. 
First of all, when I started the program with an option to define my IPv6 
Home network it chocked on the subnetmask etc. It seemed that it completly 
couldn't make anything of an IPv6 subnet or IPv6 interface address.

[root at ...1230... src]# ./snort -i xs4all -v -h 3ffe:8280:10:490/64
Initializing Output Plugins!
ERROR: Bad CIDR block [64:64], 1 to 32 please!
Fatal Error, Quitting..

The information of the interface:
10: xs4all at ...8001...: <POINTOPOINT,NOARP,UP> mtu 1480 qdisc noqueue
    link/sit 217.120.100.16 peer 194.109.5.241
    inet6 3ffe:8280:0:2001::147/127 scope global
    inet6 fe80::d978:6410/128 scope link

This is the external interface of my router. 

If I remove the home option of the command, the following happens:

[root at ...1230... src]# ./snort -i xs4all -v
Initializing Output Plugins!
Running in packet dump mode
Log directory = /var/log/snort

Initializing Network Interface xs4all
OpenPcap() device xs4all network lookup:
        xs4all: no IPv4 address assigned

        --== Initializing Snort ==--

Version 2.0.0beta-ipv6 (Build 42)
By Martin Roesch (roesch at ...1935..., www.snort.org)
Segmentation fault (core dumped)

The fact that there is no IPv4 address assigned to this interfase, is normal 
for this is an IPv6 only interfase. For the rest, there is a core dump so I 
don't have anything more.

Greetings,
Jan Hugo Prins
